electrode
An electrical conductor that enables the transfer of electric current between a metallic conductor and a nonmetallic medium, such as a liquid, a gas, or a semiconductor.
Beim Schweißen entsteht durch den Strom zwischen der Elektrode und dem Werkstück ein Lichtbogen.
During welding, an arc is created by the current between the electrode and the workpiece.
'Elektrode' (electrode) is an international technical term. It comes from Greek and is made up of 'elektron' (for electricity) and 'hodos' (way/path). So an electrode is literally a 'path for electricity'.
Die Batterie funktioniert durch eine chemische Reaktion zwischen zwei verschiedenen Elektroden.
The battery works through a chemical reaction between two different electrodes.
This word is a technical term from physics, chemistry, and engineering. You find it especially in contexts such as batteries, welding, electroplating, or medicine, for example in an ECG.
Für die Messung der Gehirnströme wurden dem Patienten Elektroden am Kopf befestigt.
For the measurement of brain activity, electrodes were attached to the patient's head.
Common combinations are 'positive Elektrode' (positive electrode/anode) and 'negative Elektrode' (negative electrode/cathode). Typical verbs are 'Elektroden anbringen' (to attach electrodes) or 'anschließen' (to connect).
Achte darauf, die positive und die negative Elektrode nicht zu verwechseln.
Be careful not to mix up the positive and negative electrode.
contact
'der Kontakt' and 'die Elektrode' can both occur in technical or electrical contexts. Here, 'der Kontakt' means the point or connection through which a circuit is closed or interrupted. 'die Elektrode', by contrast, is a specific electrical conductor that carries current to a medium or receives it from one. The words can be confused because an electrode often has to make contact. Strictly speaking, however, the electrode is a component, while the contact is more the connection or contact point.
Die Ärztin befestigt eine Elektrode auf der Haut, bevor die Untersuchung beginnt.
The doctor attaches an electrode to the skin before the examination begins.
Der Kontakt im alten Schalter ist locker, deshalb geht die Lampe manchmal aus.
The contact in the old switch is loose, so the lamp sometimes goes out.
